Unfortunately, this is not an easy fix of simply changing some of your code to make it work. You appear to have a fundamental conceptual issue. At a code level, you are using wait 0.1 to stop everything happening immediately, and you don't have any command tick to advance time.

Conceptually, you need to separate the things that are there when you start and the things that happen through time. You have done this, breaking your model into the setup and go procedures as normal. But within the time progression, you need to imagine a tick as representing some specific amount of time (let's say 10 seconds). What happens within a 10s slice of time - all your evacuees move to the next node, or at least towards it or whatever.

As a first approximation:

1. replace your ask one-of type constructions with ask (that will instruct them all to do it).
2. remove the wait instruction
3. add tick as the last command in the go procedure (to advance the clock)

Then your go button will move through time every time you press it. You can edit the go button to repeatedly run the go procedure by checking the 'forever' box.
